This dataset is superseded by ICOADS Release 3, Monthly Summary
The International Comprehensive Ocean-Atmosphere Data Set (ICOADS)
is a global ocean marine meteorological and surface ocean dataset.
It is formed by merging many national and international data sources
that contain measurements and visual observations from ships
(merchant, navy, research), moored and drifting buoys, coastal
stations, and other marine platforms. The coverage is global and
sampling density varies depending on date and geographic position
relative to shipping routes and ocean observing systems. The monthly
summary time series are available at 2-degree (since 1800) and
1-degree (since 1960) spatial resolutions. Observations (22 observed
and computed parameters) taken in each month for a give spatial
latitude by longitude box are statistically summarized (e.g. mean,
median, number of observations, etc) and NOT interpolated or
analyzed to fill data voids.
All three U.S. ICOADS partners (NOAA/ESRL, NOAA/NCDC, NCAR) offer
various data access and format options. To review all available
options see the ICOADS website
IMPORTANT: The time period of data available is defined in two segments.
* ICOADS Monthly Summary Release 2.5 covers 1800 through 2007
* All data following the Release 2.5 end date is based exclusively on
real-time GTS data with minimal quality control. These data should be
considered preliminary and will be subject to change in new Releases of
